Compendium of anatomical variants: a unique variation of the sciatic nerve

The normal course of the sciatic nerve out of the
pelvis is through the greater sciatic foramen, below
the inferior border of piriformis muscle and descends
between the greater trochanter and the ischial
tuberosity (Williams, 1995). There is evidence for
anatomical variations of the course or level of
division of the sciatic nerve (Pokorny et al., 2006).
Variations of the anatomy of the sciatic nerve may
be responsible for complications related to total hip
arthroplasties.

Abstract

The normal course of the sciatic nerve out of the
pelvis is through the greater sciatic foramen, below
the inferior border of piriformis muscle and descends
between the greater trochanter and the ischial
tuberosity (Williams, 1995). There is evidence for
anatomical variations of the course or level of
division of the sciatic nerve (Pokorny et al., 2006).
Variations of the anatomy of the sciatic nerve may
be responsible for complications related to total hip
arthroplasties.
